To all whom it may concern:

When air or gas is being forced into exploded charge lowers to atmospheric presthe tank G, by action of the engine-piston, sure or pressure" of gas stored in the receivthe valves F G, should be wide open. The

' glne in operation, the valves F, G, are first controller valve A. is constructed with a hollow body H, inclosed by a casing I. having jtherebetween a water-space J.

The casing I is provided with nipples K, L, adapted respectively for attachment of water-circulating pipes K", L ,'see Fig. -l. The pipes K, L, form a part of engine Water cooling system commonly employed with internal combustion engines, and being well understood, need no further description than to say that they are suitably connected with the water supply pipes leading to and from the engine jacket. The valve-body H, has a common forrn'of dejgachable plug M, and thelatter is longitudinally bored and screw-threaded adapted to receive a stem N, having an enlargement O at its inner end. On the stem enlargement O is arranged a cap P secured by a collar 0 as shown by F ig. 2. It is intended that cap P and collar shall have longitudinal sliding movement on the stem-head O for the purpose hereinafter appearing.

Upon reference to Fig. 2 it will be noticed that the stemN is longitudinally bored,adapted to receive a rod R whose inner end is designed to rest against the inner side of the cap P. The cap P is provided with a pack-- ing disk S, adapted to be seated on a valveseat T, in the ody-portion H. It will be understood that the cap P provides a valve for closure of the opening through the valveseat T, and the same will be understood Without further description. The outer end of the valve-stem N is provided with a hollow detachable hand device U adapted to receive a spring V having balls W, TV at its ends as shown. It will be further noticed that the ball W is arranged in contact with the .outer end of the rod R, and that a setscrew A is utilized whereby to regulate tension of the spring V.

In the use of my invention, assuming the tank C is stored with sufiic-ient pressure of air or gas and it is desired tostart the enopened and then. the hand device'U of the controller A is turned until the valve, or cap P is unseated, thereby opening up passage-way leading from the tank C, through the tubular passage-way D, the valve seat T and into the combustion chamber of the engine cylinder. B. It will be understood that the controller valve A is arranged on the engine cylinder providing the'continuous passage-way for flow of the air, or gas as described. Now it is obvious that pressure of air or gas let into the engine, in rear of its piston, shown by dotted lines inv Fig. 1, will force the piston forward, that is, oppositely in movementto its in stroke, indicated by the arrow, and thereby, through movement of connecting parts, start the engine fly-wheel in motion. Before the engine piston has made a complete stroke, as above described, the valve P, is tightly seated through obvious operation of the hand-device U.

It is designed that tension of the spring V shall exert force suflicient to hold the valve P closed against charge compressing power of the en lne piston, and that being so, obviously, t e boosting or starting flowof air or .gas fed into the cylinder as stated, will be forced out through the usual exhaust port, as usual in the scavcngering operation of internal combustion en ines. After the engine is started as described, the hand device U is turned slightly, thereby to slightly reduce tension of the spring V on theadjacent end of the rod R. It is apparent that the valve P will still remain seated since it is free to slide onthe stem-headO, and it is made to thus slide through pushing movement of the rod R;- Tension of the spring V isregulated by the set-screw- A, and the same is adjusted adapted through "operation or endwise movement of the rod R, to hold the valve P securely seated against-escape of .a compressed motive char e before it is ignited, that is to say, the va ve-Pis yieldingly held seated adapted to be unseated by increased force of the exploded charge, over normal force of an. unfired compressed charge. Now with my invention, at each exhaust stroke of the engine piston, a per tion of the exploded gases is forced into the storage tank through lifting or puppet action of the valve P, and the storing action continuesuntil the pressure in the tank C equals the pressure of. an exploded charge in the engine cylinder, at which time the valve P will remain seated and the whole exploded charge pass off through the cylinder exhaust port.

Further description of the use of my invention is deemed unnecessary since the above description will render it fully understood.

I claim:

1. The combination in an engine starter, of a storage tank, a tubular passage-way providing communication between said tank and the engine-cylinder, a valve located in the tubular passage-way, the valve being constructed with an operating stem adapting it to be set at closing position, a movable seating cap on the inner end of the valve stem, yielding means onthe outer portion of the valve stem, and means oper'atively connecting said cap and yielding means.

2. In an engine starter utilizing stored air or gas as power for boosting the engine into operation, a valve adapted to control supply of the boosting medium, said valve being constructed with a hollow body having a valve-seat therein, a reciprocating valvestem, a movable seating cap on the inner end of said stem, tension means on the outer end of the stem, and a slidable rod located between said cap and tension means.

3. In an engine starter of the character means whereby tn regulate pressure of the described, a valve constructedwitha hollow tension spring.
